facility be removed therefrom for substitution in case of a fracture or undue soiling of the globe.

Another object is to provide a gas-illuminating apparatus which, from an operative standpoint, will possess a high degree of efficiency and durability in usage, and which, structurally considered, will be of the utmost simplicity consonant with the ends to be attained, being composed of but few parts, all adapted for being made at a minimum of cost and individually so formed as to be capable of being easily assembled into a neat and compact arrangement for accomplishing the purposes intended.

Other objects and advantages will be in part obvious and in part pointed out hereinafter.

W' ith these and other ends in view, this invention accordingly consists in the features of construction, combinations of parts, and arrangement of elements which will be exemplified in the embodiment thereof hereinafter described and the scope of the appli cation of which will be indicated in the following claims.

In order that the invention may be more fully understood and made comprehensible to others skilled in its relating arts, drawings illustrating a convenient manner of carrying out the same are appended as a part of this specification, and, while the controlling principles of the invention may be otherwise applied by modifications falling within the scope of the claims, the hereindisclosed embodiment is that which will ordinarily be preferable to employ in practice, and is regarded as representing substantial improvements over the many implied and obvious variations of the same.

In the appended drawings, which illustrate the invention in detailed views, like reference numerals refer to corresponding parts, of which,

Specification of Letters Patent.

To all axiom it may concern: I Be it known that I, Gronor. E. HULsn, residing at J crsey City, in the county of Hudi son and State of New J crsey, have invented certain new and useful Improvements in l Gas-Lighting Apparatus, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the l same.

This invention relates generally to sys toms of gas-burning apparatus, but it more particularly concerns improvements in a gas-illuminating apparatus in which a mantle is arranged in an inverted position. i

Indevices of the foregoing character, a ditliculty has heretofore been experienced in so arranging the parts that, while the air may properly circulate through the device when assembled, a ready removal of the parts may be effected at will. Other inherent defects in prior devices are known to those skilled in the art and need not be specifically enumerated as their elimination through the herein-disclosed invention will be more apparent from the following de scription.

The invention accordingly has in view, among other objects, the provision of an improved means whereby the globe or shade and mantle may be conveniently positioned upon the burner and may readily be simultaneously detached for purposes of repair, or otherwise, whenever desired.

Another object residing within the contemplation of this invention is an improved means for controlling the circulation of air I around the exterior of the mantle, commonly I called the wash and for effecting a I proper removal of such air when it has be- J come exhausted. l

Another object of this invention is to proi 'vide a mounting for a globe in which a globe holder will bear a semi-permanent rei lation to such globe so that the combined globe and holder may be quickly attached i to and. detached from the burner and be;

I l l l I l l l used without danger of fracture of the globe due to excessive heating. That is to say, the holder so secured to the globe that the two may be employed as a unit, without, however, rendering it diliicult to replace new unfractured lobes in its holder. This globe-holder unit may in turn be quickly affixed to the burner and with the geatest of iii tion showing the assembled improved combined globe and mantle holder, apart from the other features of the illuminating apparatus. Fig. 5 is top elevation of the device shown in Fig. 4 illustrating details not prominently appearing in the latter figure. Fig. 6 is a side elevation of the device shown in section by Fig. 4 and disclosing, in addition to features appearing on the foregoing figure, the side recess constituting the locking means. Fig. 7 is a side elevation of the retaining ring which, in conjunction with the interposed asbestos packing, forms a semipermanent part of the shade and adapts the same for easy attachment'to the holder.

In the practical carrying out of this invention, it will be found to be applicable to various forms and arrangements of lamps or burners, but as it possesses many eminent advantages when applied to mantle lamps of an inverted type, it will be conducive to clearness to describe the preferred embodiment thereof in such connection. This form is shown by the drawings, in which 1 denotes the end or nozzle portion of the bur ner, which portion, if so desired, may be in threaded or other detachable connection with the lamp body 2, as shown. In the usual practice, it will be convenient to arrange the body portion of the burner in a permanent relation with the lamp body 2, which, as here shown, is so formed at its lower portion as to properly co-act with the present described improvement of combined mantle and globe holder. To this end, the end of said nozzle 1 is preferably reduced and exteriorly threaded, as denoted by 3, to afford a convenient means whereby the holder either with or without the mantle may be securely attached to said nozzle and, at the same time, be capable of a ready removal whenever so desired.

The holder itself will ordinarily comprise three portions: a center or inner portion 4, an intermediate portion 5, and an outer portion 6, each of which will now be more specifically described. The center-portion 1 has a reduced lower end or hub 7 so constructed and proportioned as to be easily engageable with the threaded nozzle end. For this purpose, a very convenient mode of constructing such hub is to form the same of relatively thin metal or light material, which is spun or otherwise shaped so as to afford both exterior and interior threads, as will be clear from an inspection of the drawings. By this means, an outer surface is formed, which may if desired be detachably embraced by a suitable spool 8 of asbestos or like material, having attached thereto a mantle 9 of globular or like shape. At its upper end, such hub enlarges and flares outwardly in a funnel-shaped portion 10 which is provided with a suitably arranged series of perforations 11, adapted to serve as exits for the vitiated products of combustion, as will be clear from a consideration of the operation of the device. As will be perceived, such interiorly threaded hub primarily operates to secure the shade-holder to the burner, although it may be manually released by a reverse rotation, which, however, is normally prevented by a frictional or other abutment of the shade-holder against a suitable member in fixed relation to some part of the burner, such as the gas delivering conduit. The outer portion 6, which serves as a means instrumental in gripping the globe, preferably extends from the upper peripheral edge of the perforate conical intermediate portion 4 in a radially outward direction,

top-face 12 which is provided with a series of air'inlet openings 13 and which may also have a series of retaining seats 14 adapted to assist in positioning the holder against an undesirable reflex movement. -At its outer extremity, such portion extends downwardly in a direction approximately normal to the top-face, thereby affording a ring 15 which may be threaded and adapted for detachably receiving the retaining ring 19 previously aiiixed in a semi-permanent relation to the globe or shade 25.

Intermediately located with respect to parts 4 and 6 is a shield 5, which will usually depend from a suitable attachment with one or the other of said parts and preferably from the point of connection of said parts when they are formed of separate pieces. Such shield will ordinarily be of a cylindrical shape, as shown in the drawings, and, as commonly constructed, may terminate a little short of the lower end of the hub, in order that the desired circulation of air may be insured and that it may not obstruct the distribution of the light rays when made of opaque material. It will be understood in this connection that, while the various described parts are shown as separate members which have been united in a substantially permanent relationship, diverse details may be adopted, if desired. Any two or more of the parts may be integral with one another, or may be detachably joined, and other forms of union may be employed, although in ordinary practical cases, it will be found that the arrangement herein shown will be most serviceable and inexpensive. 1n the connection as here arranged, the inner member is provided with a peripheral groove within which rests an inturned edge 16 of the shield 5, and also the inner peripheral edge 17 of the shade holder. Such parts will ordinarily be spun or stamped into the requisite shape.

The means for securely retaining the globe may now be considered. As preferred in this connection, the globe, which may be of the imperforate type, has at its mounting thereby affording a flat end, here shown as the upper end an annular groove within which rests a flat packingring 18 of asbestos or other suitable material. A retaining ring 19 embraces such asbestos packing and forces the same with suflicient pressure against the shade or globe to securely hold the parts together. At some suitable point on the periphery of such retaining ring, a portion is cut away, forming a recess 20 and the edges 21 of such recess are sprung out and adapted for being engaged with a similarly-formed edge 22 upon the globe-holding portion 6. This will be clearly understood by reference to Figs. 2 and 3, and need not be further enlarged upon. It will be clear that such expedient will be exceedingly effective in practical use and will positively retain the members in the proper relationshiy thereby preventing any inadvertent separation thereof.

It will be seen that the herein-described invention is one well adapted for attaining the objects and ends hereinbefore stated.

The device is adapted for being easily affixed to any suitable burner apparatus and is such as will possess great durability in service. The globe having the holder at tached thereto in the semi-permanent relation may be used as a unit for the purpose of rapidly replacing globes on burners by screwing the hub on and off a threaded conduit, so as to frictionally or otherwise engage another portion of the holder with a member having a fixed relation to the burner. Such attachment will be made by merely screwing the hub device onto the threaded nozzle and rotating the same until the upper face 12 abuts the lower portion 23 of the lamp. The latter carries a spring clip 24: whose end will interfit with one of the seats 14 and thereby prevent a reverse motion of the holder. iVhen assembled, as shown by Fig. l, and in operation, the fresh air will enter through the peripheral orifices 13, course downwardly along the outer side of the shield 5 and ultimately impact with the mantle 9, thus supplying the necessary oxygen for the combustion of the illuminating gases. Subsequently, such air, which has become vitiated and heated, will arise on account of its buoyancy and pass along within the shield 5, ultimately escaping through the apertures 11 and thence up through the lamp body to the surrounding air and away from the inspirator. During this operation, the requisite supply of fresh air is afforded to the mantle and, at the same time, undue fluctuations owing to currents of air are avoided and the best illuminating effect can be thereby obtained.

As many changes could be made in the above construction and many apparently widely different en'ibodiments of my invention could be made without departing from the scope thereof, I intend that all matter contained in the above description or shown in the accompanying drawings shall be in terpreted as illustrative and not in a limiting sense.
